Most popular, proven, and appraised wearable AR devices

Augmented reality is the solution for combining real-world experiences with digital add-ons. AR erases boundaries between what’s palpable and computer-generated, carrying previously unknown potential. 

Industries benefiting from augmented reality extend from manufacturing, automotive, energy to medical fields, chemical, construction, and many others. Anywhere companies face challenges with knowledge management, efficient training, and access to sought-after experts, AR can be implemented successfully. 

Augmented reality & virtual reality

AR differs from VR, as it provides an additional layer of information to our view of the real world, instead of replacing it. Augmented reality is a modern way of presenting information in a certain context – either in the context of the space that surrounds us or in the context of the activity that we perform. To learn more about differences, check out our article on AR & VR.

Depending on needs, the digitally created added layer can serve various roles, from personal spaces and entertainment to heavy-duty industrial applications, transforming the way companies function in times of Industry 4.0. AR potential in professional areas is constantly growing, and industrial companies can make great use of technology. 

Smartphones & tablets

Using AR applications with popular handheld devices is one of the possibilities to try out whether augmented reality is what your enterprise needs (the other way you’ll find at the bottom of this post). This lowers the entry threshold for users who aim to introduce AR in their workplace, without making bigger investments. Devices with iOS 11.0 or Android 7.0 and later will mostly have AR software integrated, and should give a foretaste of augmented reality applications. 

Using AR on handheld devices doesn’t provide an immersive experience nor show the full potential of technology. While some functionalities can be accessed via smartphones or tablets, only wearable devices allow users to work hands-free, focusing fully on the digital content and performing tasks. Additionally, the most common handheld devices are more vulnerable to damage, caused by e.g. dropping on the ground, or not being suited to withstand high temperatures, dust, or high humidity. Depending on the conditions, many industrial-grade applications need heavy-duty equipment, with only some devices meeting requirements (which applies to both handheld and wearables).

While it’s possible to use AR – to a limited extent – on everyday devices, smartphones, and tablets, its full potential unfolds while paired with dedicated equipment. The decision on which model to use depends to a large extent on the conditions in the work environment and planned scope of work. (Un)fortunately, there’s no one-size-fits-all solution, perfect in every aspect. Some glasses are more suitable for many-hours use than others, while particular models stand out with their robustness and adaptation to harsh environments. 

Augmented reality glasses

The go-to solution for augmented reality applications. The most important advantages include their convenience, as users can operate most devices using voice commands and gestures while performing their duties. Features differ between models, predestining devices for particular usages.

Crucial qualities of industrial-grade AR wearable devices include

• Full mobility
• Hands-free operation 
• Resilience to various conditions
• Lower risk of damage in comparison to handheld devices
• No interference with safety equipment

Working in harsh environments

RealWear HMT 1/1Z1

Specs:

With good, also outdoors, display readability and voice control up to 95 dBa of typical industrial noises, the HMT-1 is a go-to device for demanding environments. The very rugged, heavy-duty piece is suitable for industrial uses, enabling remote support, real-time communication for approximately 8-10 in one go. Adjustable to all head sizes, left and right eye compatible.

The broad scope of voice control combined with excellent noise reduction enables efficient hands-free operation of the device. The software development kit (SDK) provided by RealWear supports the creation of bespoke commands, expanding the scope of possible actions. The HMT-1Z1 model additionally presents no ignition risks in hazardous areas per Class 1 Division 1 and ATEX & IECEx Zone 1 certifications. The device can be used in areas containing explosive gases in the atmosphere in regular operation. The Intrinsically Safe improvement was introduced at the expense of smaller memory capacity, an older version of the Android system, and a lack of hot-swappable battery, with a significantly higher price. On the downside of both versions, a slight shift in the display’s position can disturb readability and these models may often require repositioning to recover proper adjustment. 

RealWear Navigator 500

Specs:

In comparison to its predecessor, the Navigator has an improved display, resulting in significantly greater readability. Previous RealWear models were prone to display distortions each time the device was even slightly touched. The boom arm underwent changes, making it easier to adjust the display without putting much strength into the positioning. The new device gained physical programmable buttons to boost efficiency, without affecting the use of voice commands, and improved security on the operating system level.

Navigator glasses are lighter and more convenient in various aspects, being given a physical battery indicator, fingerprint sensor, QR codes logging in, new support options, including an onboarding app to easily introduce the user to the equipment. Moreover, the Navigator is modular, giving users the freedom to swap desired elements to suit current needs.

The glasses make use of the superpixel technique, enabling 16 MP images rendered with the maximum brightness, not to be underestimated while working in dimly lit surroundings. As in the case of earlier RealWear equipment, Navigator’s SDK enables creating of custom solutions and commands. The new device has significantly more computational power, showing serious progress from previous models, where power limitations restricted the development of custom solutions. The Navigator doesn’t support the GApps Project, and the new shape of the battery results in a shorter working time (5-8 hours). With a premier subscription, users will gain extended support, access to the RealWear Cloud, and training for $300/year. More about the device you will find out here.

Service procedures, training – outdoors

Vuzix M4000

Specs:

Equipped with a see-through, crystal clear display, supporting left and right eye use, Vuzix M4000 is one of the lightest AR devices. Known for a long time, the smart glasses can be operated using 3 standard buttons, voice control, and a touchpad. Notably, the built-in pad tends to lack sensitivity and be difficult to operate wearing gloves.

The M4000’s rather fragile frame and voice control insufficient in noisy environments make it a better fit for service procedures and training in less demanding surroundings. Software development kits available for voice commands are moderately operational, not supporting all capabilities, but compatible with other providers’ SDKs.

Service procedures, training – indoors

Microsoft HoloLens 2

Specs:

With spatial mapping and 6 freedom degrees, HoloLens 2 supports efficient work, while the Microsoft Mesh platform enables real-time team collaboration. Users can choose from over 200 enterprise-ready solutions delivered by Microsoft. Instead of typing login details, the device can be accessed with iris recognition.

HoloLens 2 offers an exceptional experience with 3D holograms and interactions between the virtual and real world, making the device perfect for training where actions more advanced than displaying simple tutorials are required. Relatively sturdy, compatible with hardhats (utilizing a dedicated adapter), and operable using protective gloves, HoloLens 2 can be used in moderate industrial conditions. On the downside, HoloLens 2 is heavy, not suitable for working full shifts, also due to short battery life, and difficult to use outside, as holograms won’t display properly against bright backgrounds. 

Magic Leap 1

Specs:

The Magic Leap’s waveguide display creates a convincing depth effect by bending light into different layers of the display. Relatively lightweight and comfortably built, the device can be worn continuously for as long as the battery life allows. Due to its close fit, Magic Leap doesn’t let users wear correction glasses underneath. While prescription lens inserts can be installed, they’re costly and can be only within a narrow range of sight defects.

Similar to the HoloLens 2 when it comes to advantages in rather moderate conditions, in the long run, Magic Leap is less comfortable for advanced industrial use. To fully benefit from the potential of the device, users should utilize the handheld controller, leaving Magic Leap out of the fully hands-free, voice-operated AR devices. 

Remote support

Vuzix M300 Smart Glasses

Specs:

The lightweight Vuzix M300 is adaptable to left or right eye use. Depending on the external battery choice, operating time can vary from 2 to 12 hours, making it a suitable choice for day-long work. The device is designed to be water and dust-resistant but doesn’t have an IP rating, making it more suitable for indoor use in less demanding surroundings. Vuzix M300 can successfully answer the needs of users looking for a less complicated solution, yet still offering bigger potential than smartphones and tablets in conducting AR-powered training. 

Lenovo ThinkReality A3

Specs:

Ultraportable, versatile, and compatible with a number of mobile ThinkPad workstations, A3 Smart Glasses are a device suitable for performing employee training, service, and maintenance tasks. Tethering to the compliant computers or smartphones improves productivity and security, as A3 glasses keep confidential data secret, allowing only users to access it on their virtual monitors.

Lightweight frames that fit like sunglasses leave full freedom of movement, adding an immersive experience to executed tasks. Users can access 3D visualizations, digital workflows, access tutorials, and perform remote support, collaborate in real-time, and set up virtual monitors in their AR workspace. On the downside, the SDK is invitational and restricts the number of applications that can be created for the device. ThinkReality A3 requires high-performance PCs to perform optimally but calls for dedicated equipment, as it’s not compatible with all PCs. Not suitable for demanding environments, requires using hands, and a permanent connection to a mobile device. 

Epson MOVERIO BT-40

Specs:

See-through glasses with a smart touchscreen controller. Durable, flexible, and easy to wear, even while performing few-hour tasks. Moverio BT-40 can be used together with correction glasses and supports head movement tracking. The device ensures full privacy of displayed materials and is compatible with other devices thanks to the USB-C port.

The privacy aspect left its mark on the device, as Epson decided to not include a camera in this model (the sisterly model, BT-40S is however equipped with one), explaining this move as more privacy-preserving, making it inevitably less useful in professional settings – e.g. not supporting hand gestures. Suitable for employee training and displaying instructions, yet leaving a gap in two-way real-time communication with remote experts and trainers.
